TYPE-BAR FOR TYPE-=WRITENG MACHENES- Specification of Letters Patent.

Patented June 5, 1906.

Application filed June 25,1904. Serial No. 214,137.

1'0 aZZ whont it may concern:

Be it known that I, FRANS A. PETERSON, a citizen of the United States,residing at Syracuse, Onondaga county, State of New York, have inventedcertain new and useful Improvements in Type-Bars for Type-WritingMachines, of which the following is a specification.

This invention relates to improvements in type-bars for type-Writingmachines, and especially in type-bars of theclass illustrated in LettersPatent No. 747,545, dated December 22, 1903. The type-bar described inthis patent consisted. ol a single piece of metal, the U shapedbcaringguard being formed either by constructing the bar of folded sheetmetal or by milling a slot in the end of a solid bar.

The present invention relates to a type-bar of improved structure whichis cheaper to manufacture and more satisfactory than t ,-*pe-barsconstructed in the manner above set forth.

The invention will now be described in dotail, rcierence being had tothe accompanying drawings, in which F'gure 1 is a side view of one of{he improved type-bars. Fig. 2 is a view of the shield or pivotal endbefore bending. Fig. 3 shows the shield doubled and ready to receive thebar proper. Fig. 4 is a side view of the blank for the bar proper. Fig.5 is a View similar to Fig. 1, one side of the shield being removed.Fig. 6 is a section on the line 6 of Fit-r. 1

Referring to the drawings, a indicates the type-bar proper, which ispreferably punched or otherwise formed from sheet-steel of suitablethickness. This bar has a head 1 at one end to receive the type and anupwardly-projecting eye 2 at the other end to which a link may beconnected for operating the bar.

The U-shaped pivotal end P) is also punched or formed from thin flatmetal, preferably steel. The original blank is in the form shown in Fi2, but without crforations. It is then pcr iorated with suitabliarivet-holes 3 and with holes 4 for the type-bar pivot. The blank b isthen bent double along its middle line into the form shown in Figs. 1and 3, in

which the pivotal end 5 is substantially U- shaped, with the pivot-holes4 4 in line or registering with each other. The bar-blank a is providedwith suitable rivet-holes 6, corresponding to the rivet-holes in thebearing blank I), and when the parts are assembled. these holes 3 6register, and the parts may be connected by rivets, as shown in Figs. 1and 5. Other means of connecting the bar might be used, such as brazingor soldering.

It will be noted that the blank I) has two wings 7, separated by aY-shapcd space 8, the two wings beingunited by a central portion 9,which is less than half the length of the blank. On account of the smallamount of metal along the central line 9 the bending is accomplishedwith slight power. The Y- shaped notch terminates in a narrow slot 10,having a square inner cud. In assembling the parts the wings 7 lit andconform to the end of the bar c, while the eye 2 projects through theslur. l0 and. l its closely against the end of the slot to prevent dirtor rubbings from the platen entering the type-bar joint. The object inmaking the bearing of the typebar U la:|p0(l, as above described, is toprotoolthe typo-bar hearing from dust and dirt and also to provideparallel bearing-laces adjacent to the pivot to steady and guide thetype-bar, as set forth in the above-mom tioned patent.

The improved two-part typcbar described is cheaper and easier tomanufacture and its bearing can be made more accurately and of bettermaterial than a hearing which is integral with the bar, whether foldedor milled. Furthermore, the manufacture can be carried on with lighterand less expensive machinery.

Having described my invention, what I claim, and desireto secure byLetters Patent,

1. In a two-part type-bar for type-writing machines, the combinationwith a bar a having a head 1 and an eye 2, of a U-shaped hearing and(lust-shield having wings extending along said bar both in front and inrear of said eye, and means for connecting said bearing portion withsaid bar.

2. In a two-part type-bar for typo-writing machines, the combinationwith a bar proper having a suitable head 1, of a folded U- shapedbearing having its closed side uppermost to form a dust-shield andhaving two 5 projecting wings "embracing said bar, and Witnesses:
